Hi there.
I have a MK1 ford transit connect 2004 reg plate. over the last few days when I drive my van along the road in 5th gear at around 55-70 mph (2.5k rev approx) the engine and thus vans rattles heavily at this speed and gear selection when the accelerator pedal is engaged. When the foot is taken off the accelerator the rattling stops (including when the van is travelling 55-70 mpg @ 5th gear selection). It also is the case when the van is in 4th gear though the rattling isnt as severe. I know it isnt an internal engine issue as the rattling would still be present when my foot is off the accelerator. I suspect I have now a dodgy/faulty exhaust system but I thought id get a consensus of opinion of more experienced mechanics to know for sure. Does anyone know with this information that I its most likely the exhaust system is at fault. I shall gratefully await replies from anyone who can help
